An inverter with an amplitude pulse width (APW) architecture that generates a single phase AC (Alternating Current) power waveform is disclosed. The inverter generates a multi-level stepped voltage waveform, each step of the multi-level stepped waveform having a modulated width of a selected voltage. The inverter further comprises a soft fuse protection system. This disclosure also relates to a personal power plant system using said inverter and a method to generate an AC power sine wave with reduced harmonic distortion.
